摘要： The present invention is directed to an inner focusing zoom lens barrel provided with cams of a well-balanced configuration for smooth zooming and/or focusing operations, which attains sufficient performances at the minimum object distance, which is capable of inhibiting a focal length from varying throughout the entire zoom range, and which has a reduced outer diameter. The inner focusing zoom lens barrel has a fixed barrel, first and second cam barrels, a linear-shuttle barrel, a focusing cam barrel, a zooming relay barrel, and a 1st-lens-group sliding barrel, characterized in that the first cam barrel, the linear-shuttle barrel, and the focusing cam barrel are superposed one over another in this sequence inside the fixed barrel while the zooming relay barrel, the second cam barrel, and the 1st-lens-group sliding barrel are superposed one over another in this sequence outside the fixed barrel. The first cam barrel is formed with 3rd- and 4th-lens-group guiding cams, the linear-shuttle barrel is formed with 2nd-lens-group guiding cams, the zooming relay barrel is formed with 1st-cam-barrel guiding cams, the second cam barrel is formed with 1st-lens-group guiding cams, and the focusing cam barrel is formed with 2nd-lens-group focusing/guiding grooves and 2nd-lens-group guiding grooves.

摘要： The present invention is directed to a compact zoom lens that attains a reduction in outermost diameter of the lens barrel and weight and that greatly enhances a forward stroke of a first group of lenses. The compact zoom lens has a telescopic structure of a grouped-lens sliding frame, a first cam barrel, and a linearly movable barrel underlaying a fixed barrel one over another in this order, with a second cam barrel overlaying the same. Both the lens-group sliding frame and the first cam barrel are fixed in rotational direction and are engaged with each other so as to enable a relative rotation with each other along the optical axis, and the rotation of the first cam barrel is transmitted to the second cam barrel by means of the lens-group sliding frame.

摘要： The invention is directed to provide a high zoom ratio lens that can be configured to be efficiently downsized and to effectively attain sufficient compensation rate for focusing a lens component in any type of zoom ranges. The high zoom ratio lens comprises a focusing lens (B) that moves forward and backward while simultaneously moving in a circumferential direction during zooming and focusing, and a focusing cam barrel (9) that includes a first focusing cam (103) moving the focusing lens (B) during the focusing, a zooming cam (100) moving the focusing lens (B) during the zooming, and a second focusing cam (102) compensating for a displacement of the first focusing cam (103) and a telescopic movement of the focusing cam barrel (9) in any of zoom ranges. The high zoom ratio lens further comprises a stud (C) that is engaged with the zooming cam (100) and moves within a range corresponding to circumferential movement of the first focusing cam (103).

摘要： A high zoom ratio lens with a reduced number of barrel components or elements of a telescopic barrel having a light-weight outermost diameter. The zoom lens comprises first to fourth groups of lenses, a fixed barrel, a first cam barrel inside the fixed barrel, a linear barrel inside the first cam barrel, a focusing cam inside the linear barrel, and a second cam barrel outside the fixed barrel and rotatably connected to the first cam barrel. The first group of lenses move for zooming by a second—A cam in the linear barrel, and either third or fourth group of lenses move for zooming by a cam in the first cam barrel. The second group lenses move for focusing by a second—B cam in the focusing cam.
